Description

Die Erfindung betrifft ein vorzugsweise extrudiertes Fenster- oder Tür-Hohlkammerprofil gemäß dem Oberbegriff des Anspruchs 1. Ein solches Hohlkammerprofil weist mindestens eine Armierungskammer auf, die zum Aufnehmen eines vorzugsweise metallischen Armierungselements ausgebildet und vorgesehen ist. Die Armierungskammer ist auf wenigstens zwei Seiten von einer Anordnung aus wenigstens zwei sich in einem lichten Abstand und parallel zueinander erstreckenden Profilstegen gebildet, wobei eine dieser Anordnungen auf einer Seite angeordnet ist, die einer in einem Montagezustand äußeren seitlichen Profilwandung zugewandt ist. Bei der genannten Anordnung ist ein der Armierungskammer abgewandter Profilsteg nicht über einen oder mehrere seitliche Stege an der äußeren seitlichen Profilwandung abgestützt.The invention relates to a preferably extruded window or door hollow chamber profile according to the preamble of claim 1. Such a hollow chamber profile has at least one reinforcing chamber which is designed and provided to accommodate a preferably metallic reinforcing element. The reinforcement chamber is formed on at least two sides by an arrangement of at least two profile webs which extend at a clear distance and parallel to one another, one of these arrangements being arranged on a side which faces an outer lateral profile wall in an assembled state. In the arrangement mentioned, a profile web facing away from the reinforcement chamber is not supported on the outer lateral profile wall via one or more lateral webs.

Die Erfindung betrifft außerdem mit dem Anspruch 13 ein System aus einem erfindungsgemäßen vorzugsweise extrudierten Fenster- oder Tür-Hohlkammerprofil und wenigstens einem Armierungselement, vorzugsweise aus Metall.The invention also relates to claim 13, a system consisting of a preferably extruded window or door hollow chamber profile according to the invention and at least one reinforcing element, preferably made of metal.

Mit dem Anspruch 14 betrifft die Erfindung weiterhin einen Rahmen für eine Tür oder ein Fenster, der aus mehreren miteinander in Verbindungsbereichen verbundenen, vorzugsweise verschweißten, Abschnitten von erfindungsgemäßen Hohlkammerprofilen gebildet ist.With claim 14, the invention further relates to a frame for a door or a window, which is formed from several sections of hollow chamber profiles according to the invention which are connected to one another in connection areas, preferably welded.

Marktbekannte Fensterprofile weisen isolierende Kammern auf, die im Montagezustand von außen (Außenseite) nach innen (Innenseite) aufeinander folgen bzw. nebeneinander angeordnet sind. Eine oder mehrere dieser Kammern können mit Metallprofilen (Armierungselementen) ausgestattet werden, um die Stabilität des Fensters zu erhöhen. Solche Kammern werden dann als Armierungskammern bezeichnet. Die Armierungskammern sind zu den beiden übrigen Seiten des Profils (oben und unten bzw. zur Fensteröffnung und zum Baukörper/Mauerwerk hin) regelmäßig mit nur einer (PVC- bzw. allgemein Kunststoff-)Wandung abgedeckt, damit eine Verschraubung zur bzw. durch die Armierung direkt erfolgen kann.Window profiles known on the market have insulating chambers which, when assembled, follow one another or are arranged next to one another from the outside (outside) to the inside (inside). One or more of these chambers can be equipped with metal profiles (reinforcing elements) to increase the stability of the window. Such chambers are then referred to as reinforcement chambers. The reinforcement chambers are regular on the two remaining sides of the profile (top and bottom or towards the window opening and towards the building/masonry) with only one (PVC or generally plastic) wall covered so that screwing can be carried out directly to or through the reinforcement.

Obwohl vorstehend teilweise nur von Fenstern die Rede war, gilt dieselbe Problematik auch für Türprofile, weswegen nachfolgend auch einfach von "Hohlkammerprofilen" oder kurz von "Profilen" die Rede ist.Although we only talked about windows above, the same problem also applies to door profiles, which is why we will simply talk about “hollow chamber profiles” or “profiles” for short.

In Figur 1 sind verschiedene vorbekannte Hohlkammerprofile 1 mit eingesetzter Armierung 2 gezeigt, und zwar sowohl Flügelrahmenprofile (jeweils oben, mit eingesetzter Verglasung 3) als auch Blendrahmenprofile (jeweils unten, zur Befestigung an einem Baukörper). Die Außenseite (im Montagezustand) befindet sich links, während die Innenseite sich rechts befindet.In Figure 1 Various previously known hollow chamber profiles 1 with inserted reinforcement 2 are shown, both sash frame profiles (each at the top, with inserted glazing 3) and frame profiles (each at the bottom, for attachment to a building). The outside (when assembled) is on the left while the inside is on the right.

Dargestellt sind in Figur 1 weiterhin sog. Isothermen(-Linien) IL, d.h. Linien gleicher Temperatur. Innerhalb des Flügels (oben) verlaufen die Isothermen näher an der Außenseite des Profils 1 - beispielsweise verläuft die Isotherme IL1 links von der Armierung 2; im Rahmen (unten) liegt die gleiche Isotherme IL1 näher an der Innenseite des Profils 1 bzw. rechts von der Armierung 2.Are shown in Figure 1 Furthermore, so-called isotherms (lines) IL, ie lines of the same temperature. Within the wing (top), the isotherms run closer to the outside of the profile 1 - for example, the isotherm IL1 runs to the left of the reinforcement 2; In the frame (below), the same isotherm IL1 is closer to the inside of profile 1 or to the right of reinforcement 2.

Metalle haben eine hohe thermische Leitfähigkeit. Die Armierungen führen deshalb zu einer Verschlechterung der Wärmedämmung innerhalb der Konstruktion. Insbesondere die vergleichsweise große Armierungskammer bewirkt, dass in diesem Bereich praktisch keine Dämmwirkung entsteht (vgl. das praktisch vollständige Fehlen von Isothermen in diesem Bereich; Figur 1). Dadurch bildet sich in der gesamten Armierungskammer nahezu die gleiche Temperatur aus. Dies strahlt in die benachbarten Bereiche (insbesondere die sog. Falzbereiche oberhalb der Armierungskammer) aus, weshalb die Isothermen hier Verwerfungen aufzeigen und ein erhöhter Wärmeübergang festgestellt werden kann.Metals have high thermal conductivity. The reinforcements therefore lead to a deterioration in the thermal insulation within the construction. In particular, the comparatively large reinforcement chamber means that there is practically no insulation effect in this area (cf. the practically complete absence of isotherms in this area; Figure 1 ). This creates almost the same temperature throughout the entire reinforcement chamber. This radiates into the neighboring areas (particularly the so-called fold areas above the reinforcement chamber), which is why the isotherms show distortions here and increased heat transfer can be determined.

CN 110 671 003 A zeigt ein Hohlkammerprofil mit einer Armierungskammer, die an zwei Seiten, nämlich einer im Montagezustand innen liegenden und einer dem Falz zugewandten Seite, von Anordnungen aus zueinander parallelen Profilstegen gebildet ist. CN 110 671 003 A shows a hollow chamber profile with a reinforcing chamber, which is formed on two sides, namely a side lying on the inside in the assembled state and a side facing the fold, by arrangements of mutually parallel profile webs.

DE 10 2007 006 824 A1 zeigt ein Hohlkammerprofil mit einer Armierungskammer, die an drei Seiten, nämlich einer im Montagezustand innen liegenden, einer im Montagezustand außen liegenden und einer dem Falz zugewandten Seite, von Anordnungen aus zueinander parallelen Profilstegen gebildet ist. DE 10 2007 006 824 A1 shows a hollow chamber profile with a reinforcing chamber, which is formed by arrangements of mutually parallel profile webs on three sides, namely one on the inside in the assembled state, one on the outside in the assembled state and one side facing the fold.

DE 10 2014 104 190 A1 offenbart ein Kunststoff-Hohlkammerprofil, bei dem sich unter einem Teilbereich des Falzes eine sog. Haupthohlkammer befindet, in die ein Armierungselement aufgenommen werden kann. Die genannte Haupthohlkammer ist auf zwei Seiten (rechts und links) von jeweils einer Anordnung aus zwei sich in einem lichten Abstand und parallel zueinander erstreckenden Profilstegen begrenzt. DE 10 2014 104 190 A1 discloses a plastic hollow chamber profile in which there is a so-called main hollow chamber under a portion of the fold, into which a reinforcing element can be accommodated. The main hollow chamber mentioned is delimited on two sides (right and left) by an arrangement of two profile webs which extend at a clear distance and parallel to one another.

Der angestrebte ideale Zustand einer Wärmedämmung liegt vor, wenn eine gleichmäßige und regelmäßige Verteilung der Isothermen vorhanden ist und die Isothermen einen nahezu geraden, vertikalen Verlauf ohne Verwerfungen bzw. horizontale Anteile (außen-innen) aufweisen.The desired ideal state of thermal insulation exists when there is an even and regular distribution of the isotherms and the isotherms have an almost straight, vertical course without distortions or horizontal components (outside-inside).

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Hohlkammerprofil der eingangs genannten Art dahingehend weiterzubilden, dass auch bei Vorsehen einer metallischen Armierung eine gute bzw. eine gegenüber dem Stand der Technik verbesserte Wärmedämmung erreichbar ist.The invention is therefore based on the object of developing a hollow chamber profile of the type mentioned in such a way that good thermal insulation or thermal insulation that is improved compared to the prior art can be achieved even if metallic reinforcement is provided.

Die Aufgabe wird erfindungsgemäß gelöst durch ein Fenster- oder Tür-Hohlkammerprofil mit den Merkmalen des Anspruchs 1, durch ein System mit den Merkmalen des Anspruchs 13 sowie durch einen Rahmen mit den Merkmalen des Anspruchs 14.The object is achieved according to the invention by a window or door hollow chamber profile with the features of claim 1, by a system with the features of claim 13 and by a frame with the features of claim 14.

Vorteilhafte Weiterbildungen des Erfindungsgegenstands sind in den Unteransprüchen definiert.Advantageous developments of the subject matter of the invention are defined in the subclaims.

Erfindungsgemäß ist ein Fenster- oder Tür-Hohlkammerprofil, welches Hohlkammerprofil mindestens eine Armierungskammer aufweist, die zum Aufnehmen eines vorzugsweise metallischen Armierungselements ausgebildet und vorgesehen ist, welche Armierungskammer auf wenigstens zwei Seiten von einer Anordnung aus wenigstens zwei sich in einem lichten Abstand und parallel zueinander erstreckenden Profilstegen gebildet ist, wobei eine dieser Anordnungen auf einer Seite angeordnet ist, die einer in einem Montagezustand äußeren seitlichen Profilwandung zugewandt ist, und wobei bei der genannten Anordnung ein der Armierungskammer abgewandter Profilsteg nicht über einen oder mehrere seitliche Stege an der äußeren seitlichen Profilwandung abgestützt ist.According to the invention, a window or door hollow chamber profile, which hollow chamber profile has at least one reinforcing chamber, which is designed and provided to accommodate a preferably metallic reinforcing element, which reinforcing chamber is located on at least two sides of an arrangement of at least two at a clear distance and parallel to one another extending profile webs is formed, one of these arrangements being arranged on a side which faces an outer lateral profile wall in an assembled state, and in which, in the arrangement mentioned, a profile web facing away from the reinforcement chamber is not supported on the outer lateral profile wall via one or more lateral webs is.

Bei dem erfindungsgemäßen Hohlkammerprofil ist außerdem vorgesehen, dass die Armierungskammer auf drei Seiten von einer Anordnung aus wenigstens zwei sich in einem lichten Abstand und parallel zueinander erstreckenden Profilstegen (Thermo-Mantel) umgeben bzw. gebildet ist. Die Isolierwirkung wird durch noch weiter verbessert.In the hollow chamber profile according to the invention it is also provided that the reinforcing chamber is surrounded or formed on three sides by an arrangement of at least two profile webs (thermal jacket) which extend at a clear distance and parallel to one another. The insulating effect is further improved.

Bei einem erfindunsemäßen System aus einem erfindunsemäßen vorzugsweise extrudierten Fenster- oder Tür-Hohlkammerprofil und wenigstens einem Armierungselement, vorzugsweise aus Metall, ist vorgesehen, dass das Armierungselement in die Armierungskammer eingebracht ist.In a system according to the invention consisting of a preferably extruded window or door hollow chamber profile according to the invention and at least one reinforcing element, preferably made of metal, it is provided that the reinforcing element is inserted into the reinforcing chamber.

Bei einem erfindungsgemäßen Rahmen für eine Tür oder ein Fenster, der aus mehreren miteinander in Verbindungsbereichen verbundenen, vorzugsweise verschweißten, Abschnitten von erfindungsgemäßen Hohlkammerprofilen gebildet ist, kann vorgesehen sein, dass vorzugsweise in wenigstens eine der jeweiligen Armierungskammern ein vorzugsweise metallisches Armierungselement eingesetzt ist.In a frame according to the invention for a door or a window, which is formed from several sections of hollow chamber profiles according to the invention connected to one another in connection areas, preferably welded, it can be provided that a preferably metallic reinforcing element is preferably inserted into at least one of the respective reinforcing chambers.

Die erfindungsgemäß vorgesehene Anordnung aus wenigstens zwei sich in einem lichten Abstand und parallel zueinander erstreckenden Profilstegen auf wenigstens zwei Seiten der Armierungskammer wird vorliegend auch als "Thermo-Mantel" bezeichnet. Der Thermo-Mantel isoliert und dämmt die Armierungskammer erfindungsgemäß zusätzlich gegen das restliche Profil ab. Dadurch wird die Wärmedämmung des Profils an sich verbessert. Der genannte lichte Abstand beträgt bevorzugt zwischen 3 und 10 mm und höchst vorzugsweise sogar weniger als 6 mm. Dadurch wird die aus thermischer Sicht negative Entstehung von Konvektion vermindert.The arrangement provided according to the invention of at least two profile webs extending at a clear distance and parallel to one another on at least two sides of the reinforcement chamber is also referred to in the present case as a “thermal jacket”. According to the invention, the thermal jacket additionally insulates and insulates the reinforcement chamber from the rest of the profile. This improves the thermal insulation of the profile itself. The clear distance mentioned is preferably between 3 and 10 mm and most preferably even less than 6 mm. This reduces the development of convection, which is negative from a thermal perspective.

Vorteilhaft ist eine Weiterbildung des erfindungsgemäßen Hohlkammerprofils, bei der wenigstens ein Profilsteg, der einem Innenraum der Armierungskammer zugewandt ist, an seiner der Armierungskammer zugewandten Innenseite eine Anzahl von Vorsprüngen aufweist. Die Armierung wird so gegenüber dem Profilsteg der Armierungskammer auf Abstand gehalten, was die Dämmwirkung ebenfalls verbessert.A further development of the hollow chamber profile according to the invention is advantageous, in which at least one profile web, which faces an interior of the reinforcing chamber, has one on its inside facing the reinforcing chamber Has number of projections. The reinforcement is kept at a distance from the profile web of the reinforcement chamber, which also improves the insulation effect.

Bei einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass die parallelen Profilstege paarweise untereinander über eine Anzahl von Zwischenstegen verbunden sind. Dies schafft zusätzliche Stabilität, ohne die Wärmedämmeigenschaften negativ zu beeinflussen.In another development of the hollow chamber profile according to the invention, it is provided that the parallel profile webs are connected to one another in pairs via a number of intermediate webs. This creates additional stability without negatively affecting the thermal insulation properties.

Bei einer wieder anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass zumindest einige der Zwischenstege unter einem Winkel von 90 Grad zu den durch sie verbundenen Profilstegen orientiert sind. Dies hat sich unter Stabilitätskriterien als besonders vorteilhaft erwiesen; außerdem kann die zur Herstellung des Profils erforderliche Materialmenge minimiert werden.In yet another development of the hollow chamber profile according to the invention, it is provided that at least some of the intermediate webs are oriented at an angle of 90 degrees to the profile webs connected by them. This has proven to be particularly advantageous under stability criteria; In addition, the amount of material required to produce the profile can be minimized.

Bei noch einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist dagegen vorgesehen, dass zumindest einige der Zwischenstege unter einem Winkel ungleich 90 Grad zu den durch sie verbundenen Profilstegen orientiert sind. Eine solche Anordnung kann insbesondere in Eckbereichen der Armierungskammer bzw. des Thermo-Mantels von Vorteil sein.In yet another development of the hollow chamber profile according to the invention, however, it is provided that at least some of the intermediate webs are oriented at an angle not equal to 90 degrees to the profile webs connected by them. Such an arrangement can be particularly advantageous in corner areas of the reinforcement chamber or the thermal jacket.

Eine äußerst vorteilhafte Weiterbildung des erfindungsgemäßen Hohlkammerprofils sieht vor, dass durch eine Anzahl, insbesondere zwei, der Zwischenstege und eine Anzahl, insbesondere zwei, der Profilstege oder durch einen Ansatz an einem Profilsteg, der im Montagezustand einem Baukörper zugewandt bzw. zuzuwenden ist, wenigstens eine Schraubkammer ausgebildet ist, in welcher Schraubkammer das Hohlkammerprofil eine Materialanhäufung und/oder eine Wandverdickung und/oder einen Zwischensteg aufweist. Solche Schraubkammer können beim Befestigen des Profils an einem Baukörper oder beim Befestigen von zusätzlichen Komponenten (z.B. Beschlägen) vorteilhaft sein, um die Haltewirkung zu verbessern. Konkret versteht man darunter einen abgegrenzten Raum innerhalb des Profils, durch den ein randseitig profiliertes Befestigungsmittel (insbesondere eine Schraube) geführt werden kann, mit welchem Befestigungsmittel das Profil an dem Baukörper oder der Komponente fixiert wird. Insbesondere weisen die Schraubkammern Abmessungen auf, die so gewählt sind, dass das Befestigungsmittel mit Wänden der Schraubkammer wechselwirkt (in Eingriff steht), um die Haltewirkung günstig zu beeinflussen. Die genannten Materialanhäufungen oder Verdickungen tragen ebenfalls hierzu bei.An extremely advantageous development of the hollow chamber profile according to the invention provides that at least one is provided by a number, in particular two, of the intermediate webs and a number, in particular two, of the profile webs or by an attachment on a profile web, which faces or is to face a building in the assembled state Screw chamber is formed, in which screw chamber the hollow chamber profile has an accumulation of material and / or a wall thickening and / or an intermediate web. Such screw chambers can be advantageous when attaching the profile to a building or when attaching additional components (e.g. fittings) in order to improve the holding effect. Specifically, this refers to a delimited space within the profile through which a fastening means profiled on the edge (in particular a screw) can be guided, with which fastening means the profile is fixed to the structure or component. In particular, the screw chambers have dimensions that are chosen so that that the fastening means interacts (engages) with walls of the screw chamber in order to favorably influence the holding effect. The material accumulations or thickenings mentioned also contribute to this.

Bei einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass die parallelen Profilstege angeordnet sind:

  1. a) in einem Falz-Bereich des Hohlkammerprofils, welcher Falz-Bereich zum Aufnehmen einer Verglasung oder zum Aufnehmen des Randbereichs eines beweglichen Flügels ausgebildet und vorgesehen ist, parallel zu einer Falzgrund-Fläche in dem Falz-Bereich; und
  2. b) in wenigstens einem Verbindungs-Bereich, welcher Verbindungs-Bereich sich zwischen dem Falz-Bereich und einer dem Falz-Bereich gegenüberliegenden Außenseite des Hohlkammerprofils erstreckt.
In another development of the hollow chamber profile according to the invention, it is provided that the parallel profile webs are arranged:
  1. a) in a rebate area of the hollow chamber profile, which rebate area is designed and provided for receiving glazing or for receiving the edge area of a movable sash, parallel to a rebate base surface in the rebate area; and
  2. b) in at least one connection area, which connection area extends between the fold area and an outside of the hollow chamber profile opposite the fold area.

Auf diese Weise (speziell im Fall a)) dämmt der Thermo-Mantel die Armierungskammer gegen den Falzraum oder Falz-Bereich ab, sodass die durch die Armierung gebildete Kältebrücke in ihrer Wirkung besonders gut reduziert wird. Erkennbar ist dies an den Isothermenverläufen, also den Linien gleicher Temperatur, die nun durch den Armierungsquerschnitt verlaufen. Dies ist weiter unten anhand von Figur 3 auch noch graphisch dargestellt. Somit lässt sich insbesondere eine Temperaturdifferenz von z.B. > 2°C über den Armierungsquerschnitt erreichen, d.h. es hat eine dämmende Wirkung eingesetzt.In this way (especially in case a)), the thermal jacket insulates the reinforcement chamber from the rebate space or rebate area, so that the effect of the cold bridge formed by the reinforcement is particularly well reduced. This can be seen from the isothermal curves, i.e. the lines of the same temperature, which now run through the reinforcement cross section. This is explained below using Figure 3 also represented graphically. This means that a temperature difference of, for example, >2°C can be achieved across the reinforcement cross-section, ie an insulating effect is achieved.

Der genannte Verbindungs-Bereich erstreckt sich vorzugsweise vertikal durch das Profil, nämlich - wie gesagt - vom Falz-Bereich bis zu der gegenüberliegenden Seite, die bei Blendrahmenprofilen dem Baukörper und bei Flügelrahmenprofilen dem Blendrahmen zugewandt bzw. zuzuwenden ist.The connection area mentioned preferably extends vertically through the profile, namely - as said - from the rebate area to the opposite side, which faces or is to be faced towards the building in the case of frame profiles and the frame in the case of casement profiles.

Bei einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass eine Schraubkammer in dem Falz-Bereich angeordnet ist. Somit kann in diesem Bereich die Haltewirkung gezielt erhöht werden.In another development of the hollow chamber profile according to the invention it is provided that a screw chamber is arranged in the rebate area. This means that the holding effect can be specifically increased in this area.

Bei einer wieder anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass eine Schraubkammer an einer dem Falz-Bereich gegenüberliegenden Außenseite des Hohlkammerprofils angeordnet ist. Somit kann (auch) in diesem Bereich die Haltewirkung gezielt erhöht werden.In yet another development of the hollow chamber profile according to the invention, it is provided that a screw chamber is arranged on an outside of the hollow chamber profile opposite the fold area. This means that the holding effect can (also) be specifically increased in this area.

Bei noch einer anderen Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass die genannten beiden Schraubkammern entlang einer Verbindungslinie, die sich parallel zu einer Seitenfläche oder seitlichen Profilwandung des Hohlkammerprofils erstreckt, fluchten. Dadurch kann längs der Verbindungslinie ein Befestigungsmittel durch das Profil und durch beide Schraubkammern hindurchgeführt werden.In yet another development of the hollow chamber profile according to the invention, it is provided that the two screw chambers mentioned are aligned along a connecting line which extends parallel to a side surface or side profile wall of the hollow chamber profile. As a result, a fastener can be passed through the profile and through both screw chambers along the connecting line.

Bei einer vorteilhaften Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass die Armierungskammer auf einer Seite durch eine in das Hohlkammerprofil integrierte Aussteifung, insbesondere aus Faserverbundwerkstoff, begrenzt ist. Die Aussteifung ihrerseits ist bevorzugt von einer Außenwandung des Profils beabstandet ist wird somit zu einem Teil des Thermomantels, ohne dass hierfür zusätzlicher Materialaufwand erforderlich wäre.In an advantageous development of the hollow chamber profile according to the invention, it is provided that the reinforcing chamber is delimited on one side by a stiffener integrated into the hollow chamber profile, in particular made of fiber composite material. The stiffening in turn is preferably spaced from an outer wall of the profile and thus becomes part of the thermal jacket without requiring additional material expenditure.

Bei einer besonders vorteilhaften Weiterbildung des erfindungsgemäßen Hohlkammerprofils ist vorgesehen, dass die genannte Aussteifung auf einer bei bestimmungsgemäßer Montage zu einer Gebäudeinnenseite gerichteten Seite des Hohlkammerprofils angeordnet ist. Eine solche Ausgestaltung hat sich in der Praxis als besonders gut geeignet erwiesen.In a particularly advantageous development of the hollow chamber profile according to the invention, it is provided that the said stiffening is arranged on a side of the hollow chamber profile that is directed towards the inside of the building when installed as intended. Such a design has proven to be particularly suitable in practice.

Grundsätzlich verleiht der Thermo-Mantel aufgrund seiner Doppelwandigkeit der Befestigung von Beschlägen, usw. mehr Halt und Eingriff, sodass entsprechende Schraubenauszugswerte auf ein vergleichbares Niveau wie bei Verschraubungen in Metalle angehoben werden können. Gleichzeitig ist die Bearbeitung entsprechend schneller.Basically, due to its double-walled nature, the thermal jacket gives the fastening of fittings, etc. more support and engagement, so that the corresponding screw pull-out values can be increased to a level comparable to that for screw connections in metals. At the same time, processing is correspondingly faster.

Bevorzugt wird der Thermo-Mantel über die komplette Länge der Armierungskammer, in einer (Extrusions-)Längsrichtung des Profils, doppelwandig ausgeführt, wobei bevorzugt eine thermische Verbesserung sogar an drei Seiten stattfindet, wie oben bereits beschrieben. Zusätzlich wird die Haltewirkung für eine in diesem Bereich vorgesehene Verschraubung verbessert.The thermal jacket is preferably designed to be double-walled over the entire length of the reinforcement chamber, in an (extrusion) longitudinal direction of the profile, with a thermal improvement preferably even taking place on three sides, as already described above. In addition, the holding effect for a screw connection provided in this area is improved.

Grundsätzlich ist es auch möglich, den Thermo-Mantel auf allen vier Seiten der Armierungskammer auszubilden.In principle, it is also possible to form the thermal jacket on all four sides of the reinforcement chamber.

Figur 1 zeigt Querschnitte durch konventionelle Fensterprofile bzw. Hohlkammerprofile 1 (Blendrahmen und Flügelrahmen) nach dem Stand der Technik mit Stahlarmierung 2 und mit in den Flügelrahmen eingesetzter Verglasung 3. Eine die Armierung 2 aufnehmende Kammer (Armierungskammer) 4 ist umfänglich jeweils mit einfacher Wandung ausgebildet. Es ergeben sich die einleitend detailliert beschriebenen Nachteile, insbesondere hinsichtlich der erreichbaren Wärmedämmung (Isothermen IL, IL1). Figure 1 shows cross-sections through conventional window profiles or hollow chamber profiles 1 (blind frames and sash frames) according to the state of the art with steel reinforcement 2 and with glazing 3 inserted into the sash frame. A chamber (reinforcement chamber) 4 receiving the reinforcement 2 is designed with a simple wall around the circumference. This results in the disadvantages described in detail in the introduction, particularly with regard to the thermal insulation that can be achieved (isotherms IL, IL1).

Figur 2 zeigt einen Querschnitt durch ein erfindungsgemäßes Hohlkammerprofil 1, welches vorzugsweise entlang einer Extrusionslängsrichtung EL, die sich in die Zeichenebene hinein erstreckt, aus einem Kunststoffmaterial, insbesondere PVC, durch Extrusion hergestellt wurde. Das Hohlkammerprofil 1 weist - in dem dargestellten Montagezustand - im oberen Bereich des Hohlkammerprofils 1 bei Bezugszeichen 1a eine obere Profilwandung aus, die L-förmig ausgebildet ist und einen sogenannten Falz bildet. Dieser ist bei dem hier dargestellten Blendrahmenprofil zum Aufnehmen eines Randbereichs eines nicht gezeigten Flügels (vgl. Figur 3) bestimmt. Bezugszeichen 1b bezeichnet eine untere Profilwandung, die einem nicht gezeigten Baukörper zugewandt bzw. zuzuwenden ist. Bezugszeichen 1c bezeichnet eine im Montagezustand innere seitliche Profilwandung, während Bezugszeichen 1d eine äußere seitliche Profilwandung bezeichnet. Figure 2 shows a cross section through a hollow chamber profile 1 according to the invention, which was preferably produced by extrusion from a plastic material, in particular PVC, along a longitudinal extrusion direction EL, which extends into the plane of the drawing. The hollow chamber profile 1 has - in the assembled state shown - in the upper region of the hollow chamber profile 1 at reference number 1a an upper profile wall which is L-shaped and forms a so-called fold. In the case of the frame profile shown here, this is used to accommodate an edge area of a sash, not shown (cf. Figure 3 ) certainly. Reference number 1b denotes a lower profile wall which faces or is to be faced towards a structure, not shown. Reference number 1c denotes an inner lateral profile wall in the assembled state, while reference number 1d denotes an outer lateral profile wall.

Das Hohlkammerprofil 1 weist eine Mehrzahl von Hohlkammern auf, von denen in Figur 2 nur einige mit dem Bezugszeichen 1e bezeichnet sind. Eine dieser Hohlkammern 1e ist deutlich größer als die anderen ausgebildet und dient als Armierungskammer 4, in die zur Aussteifung des Hohlkammerprofils 1 ein vorzugsweise metallisches Armierungselement 2 eingebracht werden kann, welches in Figur 2 gestrichelt dargestellt ist. Das Armierungselement 2 kann beispielsweise aus Stahl gefertigt sein, ohne dass die Erfindung hierauf beschränkt wäre.The hollow chamber profile 1 has a plurality of hollow chambers, of which in Figure 2 only some are designated with the reference number 1e. One of these hollow chambers 1e is significantly larger than the others and serves as a reinforcing chamber 4, into which a preferably metallic reinforcing element 2 can be inserted to stiffen the hollow chamber profile 1 Figure 2 is shown in dashed lines. The reinforcing element 2 can be made of steel, for example, without the invention being limited to this.

Wesentlich ist nun, dass die Armierungskammer 4 auf wenigstens zwei Seiten, gemäß der Ausgestaltung in Figur 2 sogar auf drei Seiten, von einem sogenannten Thermo-Mantel umgeben ist. Hiermit ist gemeint, dass die Armierungskammer 4 auf wenigstens zwei Seiten von einer Anordnung aus wenigstens zwei sich in einem lichten Abstand und (zumindest überwiegend bzw. im Wesentlichen) parallel zueinander erstreckenden Profilstegen gebildet ist.It is now essential that the reinforcement chamber 4 on at least two sides, according to the design in Figure 2 is even surrounded on three sides by a so-called thermal jacket. This means that the reinforcement chamber 4 is formed on at least two sides by an arrangement of at least two profile webs which extend at a clear distance and (at least predominantly or essentially) parallel to one another.

In Figur 2 ist der Thermo-Mantel mit dem Bezugszeichen 5 versehen und grafisch hervorgehoben. Die genannten Profilstege umfassen in einem oberen Bereich des Thermo-Mantels 5 einen Abschnitt der Profilwandung 1a sowie einen mit dem Bezugszeichen 6 versehenen Quersteg, der in einem lichten Abstand A1 zu der Profilwandung 1a angeordnet und mit dieser über Zwischenstege 6a, 6b verbunden ist. Dabei erstrecken sich die Zwischenstege 6a unter einem Winkel von 90° zu den Profilstegen, während der Zwischensteg 6b sich schräg zu den Profilstegen erstreckt. Im linken Bereich des Thermo-Mantels 5 umfassen die Profilstege zwei parallel zueinander verlaufende vertikale Verbindungstege 7.1, 7.2, die sich zwischen dem Falz-Bereich (Profilwandung 1a) und einer dem Falz-Bereich gegenüberliegenden Außenseite (Profilwandung 1b) des Hohlkammerprofils 1 in einem Verbindung-Bereich erstrecken. Auch die Verbindungsstege 7.1, 7.2 sind über Zwischenstege 7a verbunden; diese erstrecken sich quer zu den Verbindungstegen 7.1, 7.2. Die Verbindungsstege 7.1, 7.2 weisen zueinander einen lichten Abstand A2 auf, der von dem lichten Abstand A1 verschieden sein kann.In Figure 2 the thermal jacket is provided with the reference number 5 and highlighted graphically. The profile webs mentioned include, in an upper region of the thermal jacket 5, a section of the profile wall 1a and a crossbar provided with the reference number 6, which is arranged at a clear distance A1 from the profile wall 1a and is connected to it via intermediate webs 6a, 6b. The intermediate webs 6a extend at an angle of 90° to the profile webs, while the intermediate web 6b extends obliquely to the profile webs. In the left area of the thermal jacket 5, the profile webs include two mutually parallel vertical connecting webs 7.1, 7.2, which are connected between the fold area (profile wall 1a) and an outside (profile wall 1b) of the hollow chamber profile 1 opposite the fold area -Area extend. The connecting webs 7.1, 7.2 are also connected via intermediate webs 7a; these extend transversely to the connecting webs 7.1, 7.2. The connecting webs 7.1, 7.2 have a clear distance A2 from one another, which can be different from the clear distance A1.

Im rechten Bereich des Thermo-Mantels 5 umfassen die Profilstege zwei im Wesentlichen parallel zueinander verlaufende Verbindungsstege 8.1, 8.2, die ähnlich zu den Verbindungsstegen 7.1, 7.2 ausgebildet und angeordnet sind. Ein lichter Abstand A3 zwischen den Verbindungsstegen 8.1, 8.2 kann von den lichten Abständen A1, A2 verschieden sein. Sämtliche genannte Profilstege können gleiche oder unterschiedliche Wanddicken aufweisen. Vorliegend ist insbesondere der durch die Profilwandung 1a gebildete Profilsteg deutlich dicker ausgeführt, als die restlichen Profilstege.In the right area of the thermal jacket 5, the profile webs include two essentially parallel connecting webs 8.1, 8.2, which are designed and arranged similarly to the connecting webs 7.1, 7.2. A Clear distance A3 between the connecting webs 8.1, 8.2 can be different from the clear distances A1, A2. All of the profile webs mentioned can have the same or different wall thicknesses. In the present case, in particular, the profile web formed by the profile wall 1a is made significantly thicker than the remaining profile webs.

Die Abstände A1-A3 betragen bevorzugt jeweils zwischen 3 und 10 mm. Höchst vorzugsweise betragen sie jeweils weniger als 6 mm, d.h. 3 bis 6 mm, um eine Konvektion nicht entstehen zu lassen.The distances A1-A3 are preferably between 3 and 10 mm. Most preferably they are each less than 6 mm, i.e. 3 to 6 mm, in order not to allow convection to occur.

Der Verbindungssteg 8.2 ist an seinem oberen Ende im Bereich der Profilwandung 1a leicht abgeschrägt ausgebildet, sodass in diesem Bereich kein exakt paralleler Verlauf zu dem Verbindungssteg 8.1 gegeben ist. Eine derartige Ausgestaltung soll im Rahmen der vorliegenden Erfindung jedoch mit umfasst sein. Auch die Verbindungsstege 8.1, 8.2 sind über Zwischenstege 8a verbunden, wie dargestellt. Zudem ist der Verbindungssteg 8.2 seitlich über weitere Stege 9 an der inneren, seitlichen Profilwandung 1c abgestützt.The connecting web 8.2 is designed to be slightly bevelled at its upper end in the area of the profile wall 1a, so that there is no exactly parallel course to the connecting web 8.1 in this area. However, such a configuration should be included within the scope of the present invention. The connecting webs 8.1, 8.2 are also connected via intermediate webs 8a, as shown. In addition, the connecting web 8.2 is supported laterally via further webs 9 on the inner, lateral profile wall 1c.

An einigen der Armierungskammer 4 zugewandten Innenseiten weisen die betreffenden Profilstege, vorliegend der Quersteg 6 und der Verbindungssteg 7.2, Vorsprünge 10 auf, die bei eingesetztem Armierungselement 2 dafür sorgen, dass das Armierungselement 2 nicht vollflächig an den bzw. allen Wänden der Armierungskammer 4 anliegt.On some of the inner sides facing the reinforcing chamber 4, the relevant profile webs, in this case the transverse web 6 and the connecting web 7.2, have projections 10 which, when the reinforcing element 2 is inserted, ensure that the reinforcing element 2 does not rest on the entire surface of the or all walls of the reinforcing chamber 4.

An der unteren Profilwandung 1b weist das Hohlkammerprofil 1 einen außenliegenden Ansatz 11 auf, der sich quer zur Extrusionslängsrichtung EL erstreckt. Der Ansatz 11 umfasst einen Zwischensteg 11a und kann als zusätzliche Schraubkammer für ein (nicht gezeigtes) Befestigungsmittel, beispielsweise eine Befestigungsschraube, dienen, dass/die entlang einer Befestigungsachse BA durch das Hohlkammerprofil 1 hindurchgeführt wird, um das Hohlkammerprofil 1 mit dem (nicht gezeigten) Baukörper (unten in Figur 2) zu verbinden. Auch der Thermo-Mantel 5 fungiert dort, wo ihn die Befestigungsachse BA schneidet, als zusätzliche Schraubkammer, was eine Haltewirkung des Befestigungsmittels verbessert.On the lower profile wall 1b, the hollow chamber profile 1 has an external extension 11, which extends transversely to the longitudinal direction of extrusion EL. The approach 11 comprises an intermediate web 11a and can serve as an additional screw chamber for a fastening means (not shown), for example a fastening screw, which is passed through the hollow chamber profile 1 along a fastening axis BA in order to connect the hollow chamber profile 1 with the (not shown) Building structure (below in Figure 2 ) connect to. The thermal jacket 5 also functions as an additional screw chamber where the fastening axis BA intersects it, which improves the holding effect of the fastener.

Figur 3 zeigt ein Hohlkammerprofil doch unter anderem mit eingesetzter Armierung bzw. eingesetztem Armierungselement 2. Der in Figur 3 dargestellte Gegenstand der Erfindung fällt nicht unter die vorliegenden Ansprüche, erleichtert aber das Verständnis der Erfindung. Bei Bezugszeichen 1' ist außerdem ein weiteres Hohlkammerprofil dargestellt, welches Teil eines Flügelrahmens mit eingesetzter Verglasung 3 ist. Figure 3 shows a hollow chamber profile with, among other things, inserted reinforcement or inserted reinforcing element 2. The in Figure 3 The subject matter of the invention presented does not fall within the scope of the present claims, but makes the invention easier to understand. Reference number 1' also shows another hollow chamber profile, which is part of a sash frame with glazing 3 inserted.

Das Flügelrahmenprofil 1' weist keinen Thermo-Mantel auf.The sash frame profile 1 'does not have a thermal jacket.

Aus Gründen der Übersichtlichkeit sind in Figur 3 nicht alle Elemente aus Figur 2 nochmals explizit bezeichnet.For reasons of clarity, in Figure 3 not all elements Figure 2 explicitly stated again.

Es sei nun noch auf einige Unterschiede zwischen dem Hohlkammerprofil 1 gemäß Figur 3 und dem Hohlkammerprofil 1 gemäß Figur 2 näher eingegangen: Das Hohlkammerprofil 1 gemäß Figur 3 weist bei Bezugszeichen 12, 12' ab Werk in das Hohlkammerprofil 1 integrierte (ko-extrudierte) Versteifungen aus einem Faserverbundwerkstoff auf. Gemäß der Ausgestaltung in Figur 3 bildet eine dieser Versteifungen 12' die rechte Begrenzung der Armierungskammer 4, während die Armierungskammer 4 oben und auf der linken Seite im Wesentlichen so ausgebildet ist, wie vorstehend anhand von Figur 2 detailliert erläutert. Die genannte Versteifung 12' ist über einen Steg 12a seitlich an der Profilwandung 1c abgestützt.There are now some differences between the hollow chamber profile 1 according to Figure 3 and the hollow chamber profile 1 according to Figure 2 detailed: The hollow chamber profile 1 according to Figure 3 has (co-extruded) stiffeners made of a fiber composite material integrated into the hollow chamber profile 1 at the factory at reference number 12, 12 '. According to the design in Figure 3 One of these stiffeners 12 'forms the right boundary of the reinforcing chamber 4, while the reinforcing chamber 4 is designed at the top and on the left side essentially as described above with reference to Figure 2 explained in detail. The said stiffener 12 'is supported laterally on the profile wall 1c via a web 12a.

Zwischen den Verbindungsstegen 7.1, 7.2 ist im unteren Bereich, benachbart der Profilwandung 1b, eine zusätzliche Schraubkammer 13 mit zusätzlichen Vorsprüngen/Verdickungen 13a ausgebildet.Between the connecting webs 7.1, 7.2, an additional screw chamber 13 with additional projections/thickenings 13a is formed in the lower area, adjacent to the profile wall 1b.

Der Zwischensteg 11a innerhalb des Ansatzes 11 ist unterbrochen ausgebildet, wobei sich die resultierenden Vorsprünge schräg bezüglich der Befestigungsachse BA erstrecken.The intermediate web 11a within the projection 11 is interrupted, with the resulting projections extending obliquely with respect to the fastening axis BA.

Die Vorsprünge 10 innerhalb der Armierungskammer 4 sind gemäß Figur 3 im oberen Bereich (an dem Quersteg 6) sowie im unteren Bereich (innen an der Profilwandung 1b) angeordnet.The projections 10 within the reinforcement chamber 4 are according to Figure 3 arranged in the upper area (on the crossbar 6) and in the lower area (inside on the profile wall 1b).

Entlang der Befestigungsachse BA mit dem Ansatz 11 fluchtend weist das Hohlkammerprofil 1 eine zusätzliche Schraubkammer 14 auf, die zwischen dem Quersteg 6 und der oberen Profilwandung 1a nebst den betreffenden Zwischenstegen 6a ausgebildet ist. In diesem Bereich besitzt das Hohlkammerprofil 1 zusätzliche Materialanhäufungen 14a, um die Haltewirkung einer entlang der Befestigungsachse BA eingebrachten Befestigungsschraube (nicht gezeigt) zu verbessern.Along the fastening axis BA with the extension 11, the hollow chamber profile 1 has an additional screw chamber 14, which is between the Transverse web 6 and the upper profile wall 1a together with the relevant intermediate webs 6a are formed. In this area, the hollow chamber profile 1 has additional material accumulations 14a in order to improve the holding effect of a fastening screw (not shown) inserted along the fastening axis BA.

Wie man der Figur 3 noch entnimmt, verläuft eine Isotherme (bei Bezugszeichen IL2) durch die Armierungskammer 4 bzw. das Armierungselement 2, woraus sich ersehen lässt, dass aufgrund des vorgeschlagenen Thermo-Mantels 5 eine verbesserte Wärmedämmung erreicht wurde (vgl. Figur 1).How to get the Figure 3 still removed, an isotherm (at reference number IL2) runs through the reinforcing chamber 4 or the reinforcing element 2, from which it can be seen that improved thermal insulation has been achieved due to the proposed thermal jacket 5 (cf. Figure 1 ).

Schließlich zeigt die Figur 4 einen Schnitt in bzw. parallel zu einer Verglasungsebene durch einen Rahmen 20 für eine Tür oder ein Fenster, insbesondere einen Blendrahmen, der aus mehreren Abschnitten 1.1-1.4 von erfindungsgemäßen Hohlkammerprofilen 1 (vgl. Figur 2) gebildet ist. Die Hohlkammerprofil-Abschnitte 1.1-1.4 sind paarweise miteinander in Verbindungsbereichen 21 verbunden, vorzugsweise verschweißt. Bei dem gezeigten Rahmen 20 ist in jedem der Verbindungsbereiche 21 ein vorzugsweise metallisches Verbindungselement 22 in Form eines L-förmigen Verbindungswinkels mit seinen beiden Schenkeln 23 (nur für ein Verbindungselement 22 bezeichnet) in zwei miteinander verbundene Hohlkammerprofil-Abschnitte 1.1-1.4 im Bereich der jeweiligen Armierungskammer 4 (strichpunktiert) eingebracht. Es kann darin klemmendkraftschlüssig oder anderweitig (z.B. stoffschlüssig) gehalten sein, um die Verbindungsbereiche 21 zu verstärken. Diese Ausgestaltung ist hinsichtlich der Art und Anzahl der Verbindungselemente 22 nicht beschränkt.Finally, it shows Figure 4 a section in or parallel to a glazing plane through a frame 20 for a door or a window, in particular a frame, which consists of several sections 1.1-1.4 of hollow chamber profiles 1 according to the invention (cf. Figure 2 ) is formed. The hollow chamber profile sections 1.1-1.4 are connected to one another in pairs in connection areas 21, preferably welded. In the frame 20 shown, in each of the connecting areas 21 there is a preferably metallic connecting element 22 in the form of an L-shaped connecting angle with its two legs 23 (designated only for one connecting element 22) in two interconnected hollow chamber profile sections 1.1-1.4 in the area of the respective Reinforcement chamber 4 (dash-dotted line) introduced. It can be held therein in a clamping, force-fitting manner or in some other way (eg materially bonded) in order to reinforce the connection areas 21. This embodiment is not limited in terms of the type and number of connecting elements 22.

Der Rahmen 20 kann über die Hohlkammerprofil-Abschnitte 1.1-1.4 in der beschriebenen Weise mit externen Komponenten verbunden werden, z.B. mit einer den Rahmen umgebenden bzw. aufnehmenden Laibung (nicht gezeigt).The frame 20 can be connected to external components via the hollow chamber profile sections 1.1-1.4 in the manner described, for example with a soffit surrounding or receiving the frame (not shown).

Exemplarisch ist in eine der Armierungskammern 4 bei Bezugszeichen 2 eine Armierung bzw. ein Armierungselement eingebracht, wie weiter oben anhand von Figur 2 und 3 bereits detailliert beschrieben. Selbstverständlich können auch die anderen Armierungskammern 4 gemäß Figur 4 entsprechende Armierungen 2 aufnehmen. Die Armierungen 2 können sich auch bis in die Verbindungsbereiche 21 erstrecken, was in Figur 4 nicht dargestellt ist.As an example, a reinforcement or a reinforcement element is introduced into one of the reinforcement chambers 4 at reference number 2, as described above with reference to Figure 2 and 3 already described in detail. Of course, the other reinforcement chambers 4 can also be used in accordance with Figure 4 take up the appropriate reinforcements 2. The reinforcements 2 can also extend into the connection areas 21, which in Figure 4 is not shown.
